What is the physics behind self driving cars and how are waves involved in self driving cars?

Answers

Self driving cars in the pubic streets is not possible unless tracks are laid out separately for them. The cars would use selected roads and tracks and steering and driving would be automated so that a driver is not needed. Waves (telecommunications) help in data transfer and remote guidance.

There are radar, lidar, video and sonar senders and receivers, with which the computers build up an image of the surroundings. That is combined with GPS location data, and input from the operator as to destination and route. Map data is stored internally which includes speed limits and info on lights and other restrictions.

Computers put this all together and send speed, braking and steering info to the car's controls. If all goes well, you get to your destination without problems.
